JESSE A.- HEYDRICK, OF BARNHARTS MILLS, PENNSYLVANIA.

PUMP.

SPECIFICATION forming part of Letters Patent No. 254,010, dated February 2l, 1882.

Application nieu october s, rsa1. (No model.)

To alt whom t may concern:

Be 1t known that I, JESSE A. HEYDRIGK, of

Barnharts Mills, in the county of Butler and of the heavy weight of the uid, and therebylessen the danger of breaking the said rods.

The invention consists in certain peculiarities of construction and arrangement, as hereinafter described.

In the accompanying drawings, Figure l is a vertical section of my improved pump; Fig. 2, a section through theline s s .of Fig. l; Fig. 3, a section through the line t t; Fig. 4, through the line u u',- Fig. 5, through o o',- Fig. 6, through fw w; and Fig. 7, top and sectional views of the cage of ball C, and Fig. 8 is the follower.

The tubing d, extending to the top of the well, is connected tothe Workingbarrel or fol- 1ower-chamber d2 at the bottom by the intermediate case or shell, d', into opposite ends of which the said parts are screwed. The shell d at a point below its upper connection is somewhat enlarged and provided with a partition, G/havin g semicircular surfaces to forni two cylindrical chambers oommunicatin g with each other above and below the partition. A seat, G, is formed in the larger chamber, in which is tted thepfgmrlg, which consists of a cylinder bored to ht the rod a, which connects the follower K with the pump-rods. (Not shown.) 'To make a Huid-tight joint a cylindrical layer of Babbitt metal is cast around the rod a above the packer b', and covered by a pipe, b, whose lower end is screwed into the top of said packer. f The lower end of the packer b is reduced to form a collar, H, having a female thread and ports I, leading to the rod a, to break continuous packing, and the upper end of a second packer, b2, is screwed into said collar. The lower end of the shell d is provided with a seat, G2, for receiving the packer b2. This packer consists ot' two cylindrical portions, one arranged within V the Y other, and connected together by lngitndinal ribs forming ports for the passage of the tiuid. The top of the outer cylindrical portion, together with a'shonlder in the inner portion, forms a seat for the dropvalve C2, which incloses the upper part ot thel inner' or smaller portion of the packer, while a seat, b3, is screwed into the lower end of the onturcylindrical portion of the said packer for the second drop-valve, C3, which is thus inclosed within a cage formed in the packer b2.

As'the larger chamber in the shell d! is closed by the packer b', the smaller chamber constitutes a passage for the iiuid, and a seat, F, is provided in the upper end thereof for the ball-valve G, which is coniined in a cage, which is secured in position by a' set-screw, E, inserted through an opening in the shell d# It is to be observed `that the screw-connection between the packers b and b2 serves to adj ust the saidpackers to their respective seats.

The rod a is connected to the follower K by means of the valve-cage of ball-valve C4, into the top of which the said rod screws, the cage being screwed to the top of the follower. The follower K is provided with a longitudinal central bore for the passage ot' the tluid, and is constructed of two sections screwing together, thc lower end of the upper section being recessed for receiving'aunular metal rings o, and leather cups n, arranged between the rings. Thcfollower is provided near its ends with annular recesses m, formed in its outer surface, for receiving and holding any sand that may pass between the follower and the walls ot' chamber d2.

Having thus described my invention, what I claim as new,\\and desire tosecnre by Letters Patent is- 1. In apump, the combination, with the tubing d and the follower-chamber d2, of the intermediate double shell, d', having upper packer-seat, G G', and lower packer-seat, G2, and intermediate passage for fluid, substantially as shown and described, andv for the purpose set forth.

2. In a. pump, the combination, with the rod a and the shell d', having seat G, of the packer b', and the pipe b, inclosing a layer of Babbitt metal and screwing into the top ot' said packer, substantially as shown and described.

3. In apump, the combination, with the rod a., the shell d', having seat G2, and the packer b', having collar Hand ports l, of the packer b2, constructed of two cylindrical portions connected by longitudinal ribs, and having ports between the ribs, and the drop-valve C2, adapted to close said ports, substantially as shown and described.

4. In a pump, the combination of the packer b2, having acage formed in its lower portion, the drop-valve C3, arranged therein, the seat b3, screwed into the lower end of said packer. and the seat G2, substantially as shown and described.

5. In a pump, the combination ot` the shell d', its partition Gr', seat F, ball-valve C, the valve-cage, the set-screw E for holding` the cage, and means for supporting and operating the said parts, substantially as shown and described.

6. In a pump, the combination, with the chamber d2 and the rod a, of the follower K, made in two sections and having sand-recesses m and cups n. and rings o, and the valve-cage of ball-valve C4, screwed to the said rod and follower, substantially as shown and described.

7. In a pump, the combination of the shell d', having two packer-seats, the packer b, and the packer b2, connected together by a screw,

substantially as shown and described, whereby both packers shall be adjusted to their 3o seats, as set forth.

8. In a pump, the combination, with the packers b and b2, of the collar H, secured to packer b, and provided with a female thread, and ports I, leading to the rod a, substantially as shown and described, whereby the continuous packing shall be relieved, as set forth.

9. In a pump, the combination, with the rod a and shell d', ofthe packing b, b', and b2, extending continuously above and below the packer-seats, substantially as shown and described.

lO. In a pump, the combination of the double shell d', the packer b', the ball-valve C, the rod a, the packer b2, and seat b3, the drop-valves C2 Cf', the follower K, ball-valve C, and follower-chamber d2, substantially as shown and described.

11. In a pump, the combination, with a shell or chamber and the rod to, ot' the valves G2 C3 5o and the packer b2, having seats for the said valves, substantially as shown and described.
